Having thus described my invention, what I claim is- 1. In heaters and pnriliers for feed-Water, the combination of the main body A, provided vvith the partition C and corrugated partition D, forming the space E for live steam in the center and on the outside of said partition C for exhaust-steam, with the steam and water inlet and outlet pipes and arranged substantially as set forth.

2. Aheater and purifier for f eed-Water, oonsisting of thefshell A, provided with the partition O and thecorrugated partition D, in oombination with the steanrppe F, having branch pipe G, having perforated T-piece k, the water-pipe H, provided with a stean1-jet o, and the mud-drum I and the exhaust-pipes, all arranged as shown, and for the purpose specified.

3. The combination of the main body A, provided with the partition C and corrugated pipe D, constructed as shown,with the steampipe F, having branch pipe G and T-pipe 7c at the upper end and entering into the central space E at the lower end, the exhaust inlet and outlet pipe, and the Water inlet and outlet pipe, allarrangedas shown and speeiied.

In testimony whereof I affix my signature in presence of two Witnesses.
